Welcome to my astronomy blog, I dedicate myself to the simplest form of amateur astronomy which requires only portable equipments.

20080221 Quiet Sun

We finally got sunny day, seeing is low at 3/10, transparency like 8/10, better than even last night. Exposure like 1/800s can be used for surface detail, and this is rare these days. Surface activity remains low, and there're a couple of interesting but small prominences around the solar limb, nice view.
